GBT with logistic regression loss function cannot be used in cross-validation
|Reported by:||gkronber||Owned by:||gkronber|
GBT with logistic regression loss function produces a classification solution (discriminant function model) even though the problem is a regression problem.
In cross-validation we clone the problem and try to use it in combination with the models in an ensemble. This throws an exception when the problem is actually a regression problem.
